An Athens man told police Tuesday he was concerned because he's received harassing phone calls from his grandmother, who was recently released from prison for a conviction on a charge she tried to hire a hit man to kill his father and other family members, Athens-Clarke police said.

A police report didn't say what 71-year-old Ivy Jean Davis said in the calls, but the grandson told an officer he was concerned that she managed to track him down at his workplace, a restaurant on Baxter Street.

Davis pleaded guilty in March 2008 to five counts of criminal solicitation to commit murder and was sentenced to 25 years, the first five to be served in prison. She was released from prison May 6.

Authorities learned of the murder plot on May 6, 2007, when a man who rented property from Davis tipped them off that she asked him if he knew someone she could hire to kill her husband and son-in-law, according to police.

Police said they asked the man if he could get a tape recording of Davis making the request, and he was able to deliver the tape that same day.

A sting was set up for the next day between Davis and an Athens-Clarke police officer who does undercover work with the Northeast Georgia Regional Drug Task Force, police said.

The officer posed as a hit man and used a concealed camera to record a meeting with the Hull woman at a location in Northern Athens-Clarke County, according to police.

Davis told the officer she wanted him to murder her husband of 47 years and a son-in-law, and said there were even more people she wanted killed after he finished those jobs, police said.

Davis provided the officer with photographs of the intended victims, as well as instructions and maps to their homes, police said.

She also took a "substantial step" in the murder-for-hire scheme by withdrawing $200 from an ATM and giving the money to the officer so he could "buy an untraceable gun with which to commit the murder(s)," the indictment states.

As attorneys prepared the case for trial, District Attorney Ken Mauldin called the tapes "chilling."

"That undercover officer did an excellent job," Mauldin told the Athens Banner-Herald at the time. "He kept asking (Davis), 'Are you sure you want me to do this?' He gave her every opportunity to say 'no.'"

The woman's attorney argued that a psychiatrist determined his client has a disability that impedes rational thought. A lifetime of alcohol abuse caused Davis to lose the ability to control her impulses, the attorney said.

Authorities think Davis' motive in attempting to hire a hit man was financial.

In March 2008, Davis struck a bargain with prosecutors in which they dropped criminal attempt to commit murder charges in return for guilty pleas on the solicitation charges.

As part of the plea deal, Davis agreed to not have any contact with her intended victims, which did not include her grandson.

The grandson told police Davis called him at his job three times, and that he hung up on her twice and told her not to call again when hanging up on the third call, police said.

An officer explained to the man the process for obtaining an arrest warrant if he wished to pursue harssment charges.
